In this context, it is writen with the intent of assisting in the successful removal and installation of the IP-Audio sound card driver used in Livewire and AES67 environments. However, this could be used where clean-up of any inf files is needed. For manual instructions to remove other components of the IP-Audio Driver, [click here for additional documentation](/v1/docs/driver-uninstall-errors-how-to-manually-remove-the-ip-driver). ## Description With regard to versions of inf files, they are important (critical) to the successful installation of updates to the driver. As Windows updates are installed, driver versions are updated, these files can become orphaned and prevent a driver update from completing. We will use the Windows `pnputil` program ran from an "elevated" command prompt to remove these files. If you are not familiar with using command-line interfaces or do not have Administrator privileges in Windows, please contact your Administrators. ## Removing INF files 1. Locate the Command Prompt application on your computer. > [!NOTE] > You can normally find this by typing "cmd" into the search box on your computer 2. **Right-click** on the Command Prompt icon 3.

From the command prompt, run the command `pnputil -e` ![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/1a2e44ad-1613-44c4-bbbd-453ebb299c63-image.png?sv=2026-02-06&spr=https&st=2026-10-26T17%3A29%3A34Z&se=2026-10-26T18%3A29%3A34Z&sr=c&sp=r&sig=etaBjYFPcfgVpQpsDU2m18nPYPlYGhl1D%2FNTECbdCJc%3D) This command returns a print of all 3rd part inf files on your system. Your list will vary in length from what is shown here. ```plaintext Microsoft PnP Utility Published name :            oem8.inf Driver package provider :   DELL INC Class :                     System devices Driver date and version :   05/19/2015 8.2.0.454 Signer name :               Microsoft Windows Hardware Compatibility Publisher Published name :            oem16.inf Driver package provider :   Microsoft Class :                     Human Interface Devices Driver date and version :   04/08/2011 8.15.403.0 Signer name :               Microsoft Windows Hardware Compatibility Publisher Published name :            oem25.inf Driver package provider :   Axia Class :                     Network Protocol Driver date and version :   06/29/2021 2.11.3.3 Signer name :               TLS Corp Published name :            oem26.inf Driver package provider :   Axia - Telos Corp. Class :                     Sound, video and game controllers Driver date and version :   06/29/2021 2.11.3.3 Signer name :               TLS Corp C:\Users\Administrator> ``` 1. Scan through this list and make note of the **Published name:** where the **Driver Package Provider:** contains the word Axia. In this example, that is; **oem25.inf** and **oem26.inf**. 2. Remove them, one at a time, by using `pnputil` with the `-d` option (for delete). Examples are shown here ```plaintext C:\Users\Administrator> pnputil -d oem25.inf Microsoft PnP Utility Driver package deleted successfully. C:\Users\Administrator> pnputil -d oem26.inf Microsoft PnP Utility Driver package deleted successfully. C:\Users\Administrator> ``` ## Verify successful removal Re-run the command in step 4 from above and verify that the word Axia does not appear in any Driver package provider information. ## Reboot You must reboot before attempting to perform an update. Generally speaking, you should perform these steps and reboot after ANY failed update. ## Let us know how we can help If you have further questions on this topic or have ideas about improving this document, please [contact us](https://www.telosalliance.com/support-request).
